In The Triune God (The Father, The Son, and The Holy Spirit). and In the Deity Of Jesus Christ...In the Divine Person Of The Holy Spirit, who convinces the world of righteousness, sins, judgment.
He automatically baptizes all true Christians into the body of Christ at the very moment of conversion; seals them until the day of redemption...In Creation (of everybody and of all that exist) by God.
In the verbal, plenary Inspiration of the Bible: The Word Of God. That All Men Are Sinners (by birth, nature, choice...) and need to be saved by Jesus Christ. In Salvation By Grace; that is through faith in Jesus Christ only.
In The Eternal Security (of Salvation) of every true Christian In Two Special Ordinances: Water Baptism and The Lord Supper. In Water Baptism By Immersion In The Name Of The Father, and The Son, and The Holy Spirit that must follow confession of faith of the repentant sinner in Jesus as God-Savior. In The Great Commission as a priority. In Marriage as a legal union of one (1) man and one (1) woman, for as long as both shall live.
That Men And Woman Are Equal In Christ, yet with different roles at home and at the local church. That Only Jesus Gives The Power To Become Children Of God, and only to those who believe in Him and receive Him as their savior; even though we are all God's creatures that are the object of His universal love.
In The Return Of Jesus that is imminent, pre-tribulational, literal, pre-millennial for the rapture of His redeemed ones. That Hell Is A God-Prepared, Literal, Unquenchable Lake Of Fire for the eternal destiny of the devil, his angels, and all those who die without Jesus. That Heaven Is A God-Prepared, literal Place where all (living or already dead) Christians will go to live with Jesus at the rapture.
